Paper or plastic? It’s a quandary we have faced in the grocery store for decades. Plastic is non-biodegradable and usually ends up in landfills or worse, in waterways or in the ocean. On the other hand, manufacturing paper is water intensive and produces pollution.

In recent decades, the so-called hygiene hypothesis has been proposed to explain the rapid rise in allergic diseases during the 20th century and has even been linked to a broader range of chronic illnesses.
